2-2 Power Supply Unit
There are three AC Power Supply Units available, the CQM1-PA203, the
CQM1-PA206, and the CQM1-PA216, and one DC, the CQM1-PD026. Select a
Power Supply Unit that matches the current consumption of the system.
2-2-1 Power Supply Unit Components
The following diagram shows the basic components of a Power Supply Unit.
Power Indicator
Lit when power is being supplied.
External terminals
Crimp connectors should be used for Power Supply Unit wiring and should be
less than 7 mm wide. The wires should be 1.04 to 2.63 mm

Note The CQM1-PA203 weighs 460 g max. and the CQM1-PA206, CQM1-PA216,
and CQM1-PD026 each weigh 560 g max.
2-2-3 Selecting a Power Supply Unit
As mentioned previously, there are three AC Power Supply Units and one DC
Power Supply Unit. Select the appropriate Power Supply Unit based on the total
5-VDC current consumption requirements of the Units in the configured system
and the 24-VDC output terminals (PA206/PA216).
Model Number Capacity
CQM1-PA203 5 VDC, 3.6 A (18 W)
CQM1-PA206,
CQM1-PA216
5 VDC, 6.0 A; 24 VDC output, 0.5 A (30 W total)
The total power consumption from the 5-VDC supply and 24-VDC output must be less than 30 W. In
other words: 5 VDC current consumption × 5 + 24 VDC current consumption × 24 ≤ 30 (W).
CQM1-PD026 5 VDC, 6 A (30 W)
